TheDarkNeon gift: Wishes

My good friend is going through the ringer right now and I decided to do this one up for him, based on his story he wrote for 's birthday >> [link] and I was actually a part of the story! Here, He, Sammy (first time I've drawn her unARed) and me are all gathered for her birthday when she opens a gift that instantly TGs he and I and regresses the three of us to toddlers! Check out the shirts he and I have and tell me if you can guess what they're a reference to.
